STRIP GUIDER.

' Application led March 8, 1926; Serial No. 93,078.

My invention relates to an improvement in strip guiders, and has for an object the provision of a structure for guiding fabrics to a wind-up roll so that the same will be properly wound up thereon.

More specifically, my invention has for an object the provision of aguider construction adapted for use in the manufacture of oil cloth, with particular reference to the Winding or rolling up of the finished product, my

construction so controlling the cloth that the same will run straight and true about the wind up roller.

A still further object of my invention is the provision of a guider such as above in dicated which will control the material at all times as it passes to the wind-up roll or roller, the guider being so constructed and arranged as to correct at the outset any tendency of the material to deviate from the desired path of travel.

Another' object of my invention is the provision of a guider which is positively operated by the materialbeing guided, my

construction being such as to eliminate the use of solenoids or other electrical equipment, or the use of compressed air and similar apparatus. My improved construction reduces the cost of installation and maintenance to a minimum, and yet, as I have demonstrated on a commercial scale, provides an apparatus which is extremely eiiicient in operation.

Brieiiy, my invention provides two pairs of guider rollers, a pair at each side of the material to be guided, the edges of the material on its way to the wind up roller passing between these rollers. One of the rollers of each pair is pivotally mounted so as to be moved bodily under certain conditions out of pinching position with respect to its co-operating roller, this movement being ef'- v fected by the material being guided passing over a plate provided for that purpose in the path of the material, the movement of this plate, due to deviation in the direction of travel of the material, causing the plate to be swung about a pivot, to eect thereby bodily movement of the roller. The reduction of the pinching action on the material as well as the shape of the plate itself causes the material to swing back to or assume the desired path of travel.

By providing the plate above mentioned,

I effect a`positive actuation of the roller, which 1s much more desirable and pract-icable than relying upon the action of a solenoid, for instance, the circuit of which is.V

controlled by the material being guided, and

much more practicable than operating an air valve which will set mechanism in operation for actuating a roller.` Again, by my improved' construction, trip fingers, valves, switches, andthe like, which are inherently obJectionable, are entirely done away with. Iw1sh it to be noted also that the material belng guided in myconstruction passes over the actuating plate so that the face of the material, as distinguished from the mere edge thereof, is in contact therewith at all times, thus eliminating all danger of the edge of the material beinginjured and providing, so far as the actuating plate is concerned, a relatively extensive surface for the material to work on.

In the accompanying drawings, wherein I have illustrated a practicable embodiment of my invention,

Fig 1 shows my invention, more or less diagrammatically, in operation on a length of fabric; i Fig. 2 is an end elevation of one of my improved guiders, a part thereof being broken away to show interior construction;

Fig.. 3v is a side elevation ofone of the guiders; and

Fig. 4 is a plan view.

Referring to the drawings in detail, and first of all to Figs. 2, 3 and '4, l designates a stand or base on which the guider mechanism is mounted. rI`his base may be atiixed to a table or other suitable support. At the upper part of the stand a guider roller 2 is provided, mounted in a suitable bearing provided for that purpose. Immediately belowthe roller 2 is a second guider roller A3, this roller, which is bodily movable so that the relative positions of the two rollers may. be varied, being mounted in a movable bearing 4.

Inasmuch as the fabric to be guided v passes between the two rollers 2 and 3, it will be apparent that the pinch on the fabric may be varied by adjusting one of the guider rollers with respect to the other, that is to say by moving one roller at an angle to the direction of travel of the fabric being guided.

` secured to the base 1. This block receives a threaded plug 7 threaded into the block and carrying a spring 8, surrounding the pin 5, the upper end of this spring thrusting against the head on the pin 5, while the lower end of the spring rests in the bottom of the plu 7. The plug 7 being threaded, may be adJusted in the block 6 so as to regulate the thrust of the spring.

Pivotally attached to or mounted on the base or stand 1 is a lever 9 fulcrumed at 10. The pin 5 above mentioned and which supports the bearing 4 passes through the lever 9, and below this lever is provided with a nut 11 threaded thereon, whereby the movement imparted to the pin 5 by actuation of the lever 9 may be varied. The free end of the lever 9 is attached to a plate 12, interposed in the path of the fabric to be guided, by means of a connecting rod 13, the ends of which are attached to the plate 12 and lever 9 by threaded connections, whereby the effective length of the connecting rod and hence the throw of the lever 9, may be varied. The plate 12, which 1s to 'be described more in detail hereinafter, is pivoted on a rod 14, extending longitudinally of the rollers 2 and 3, this rod being carried in the base 1 and partially supported by a member 14 fixed to the block 6. The bearing above referred to is in part supported on a pivoted arm 16, pivoted at 17 in the support or base l.

It will be a parent from the description so far given t at pressure on the plate 12 to pivot the same about the rod 14 will, through the connecting rod 13 and lever 9, impart positive movement to the supporting pin 5 to permit the roller 3 to move downwardly bodily, thereby to decrease the inch of the rollers 2 and 3 on the fabric to be guided, while release of this pressure will permit the spring 8 to function to increase this pinch.

The plate 12 is so positioned, as will be apparent from Fig. 2, that the fabric F passing through the guider rollers 2 and 3 to the wind-up roll 18, will pass .over and in contact therewith. This plate likewise is slightly curved longitudinally and in addition is provided with a sloping or inclined forward' edge which I have designated 19, so that the forward edge of this plate instead of extending parallel to the longitudinal axis of the rollers 2 and 3, is deflected downwardly from the outside edge thereof. This provides a plate so constructed that the fabric F, when attempting to deviate from its prescribed path of travel, is obliged to ride up an inclined edge of the plate gradually to increase the depression of the plate 12 as the edge of the fabric approaches the outer edge of the plate. The effect of this is t0 gradually decrease the pinch of the rollers 2 and 3 on the fabric, the greater the deflection of the edge of the fabric out ofl its redetermined or desired path of travel t e more the roller 3 moves away from the roller 2, to correspondingly decrease the pinch on the fabric.

It is to be understood that two sets of these guiders are employed for the guiding of a strip of fabric, as shown in Fig. 1, a set of guiders bein provided at each side or edge of the strip eing guided.

With reference to Fig. 1, it will be apparent that with the fabric F moving in the direction of the arrow on said figure, should the fabric tend to move to the right, for example, out of the desired path of travel, this will cause the fabric to travel up the inclined edge 19 of the plate 12 of the righthand guider in said figure to cause the said plate to be depressed, this depression of the plate increasing the higher the fabric rides up the edge of the plate. The resulting depression of the plate 12 will through the connecting rod 13 and lever 9, permit the bearing 4 to lower, thereby permit-ting the roller 3 to move downwardly away from the roller 2, to relieve the pinch on the righthand edge of the fabric. Under these conditions the pinch on the left-hand edge of the fabric is the maximum, with the result that the fabric will be caused to resume its prescribed path of travel over the wind-up roller 18. I wish it to be understood that the movement of the fabric F out of its predetermined or desired path of travel is but very slight, the fabric being brought back to its normal path again before it has had an opportunity to be deflected more than but very slightly. Should the fabric tend to move to the left, as viewed in Fig. 1, the set of guider rollers at that side of the fabric will operate, that is to say, the lower roller 3 thereof will be depressed so as to relieve the pinch7 on the fabric at that edge thereof in the same manner as explained in connection with the right-hand guider hollers.

It will be seen from the foregoing therefore, that I have provided a machine or apparatus for the guiding of fabrics being wound upon a wind-up roller, whereby deflection of the fabric as it is being rolled up is eliminated or reduced to a minimum. It will be seen also that my apparatus is exceedingly simple in construction and is mechanically operated throughout, so that a strong, sturdy construction can be incorporated in the apparatus to thereby insure positive working of the apparatus at all times. This is a distinct advantage over` such types of apparatus as those employing compressed air, in which a relatively fragile valve or valve-controlling member must be operated by the fabric being guided, and

. means for adjusting my improved apparatus throughout, so that it is possible to set the machine properly when the same is first installed, thereby making it unnecessary to adjust the machine from time to time thereafter.

What I claim is:

1. In a guider for fabrics the combination of an upper ider roller and a lower guider roller an means positively actuated by the engagement therewith of the fabric being ided to vary the relative positions of sald rollers. 2. In a guider for strip fabric the combination of a pair of uider rollers and means connected to one ro ler and positively actuated by the engagement therewith of tle fabric being guided for moving one roller relatively to the other roller.
